Definitions

  • the present invention relates to a screw, a bolt or lockbolts. There is considerable competition worldwide for these products. The prices of these products are therefore very low and it is therefore an object of the present invention to provide a screw, a bolt or a lock bolt, which are much cheaper to manufacture.
  • the screw, the bolt or lockbolts can be made by a single manufacturing step of rolling, wherein also a corresponding external force attack, such as a hexagon, a hexalobular (six-round) force attack or a participatviel leopardkraftangriff in which a same manufacturing step of rolling can be made ,
  • a flange may be rolled in the screws or bolts.
  • this rolling process can even be designed so that the screw or the bolt can be provided with a captive washer in the one production step.
  • the screw according to the invention, the bolt or locking bolt according to the invention can be completely rolled in a single manufacturing step with thread, force application, flange and possibly captive mounted washer.
  • the production of the screw according to the invention, the bolt or locking ring bolt according to the invention can be significantly reduced and simplified, since the corresponding pressing or cold forming processes and the usually subsequent washing processes in the manufacture of the connecting element according to the invention can be completely eliminated.
  • the process steps of dephosphatization and heat treatment can be omitted if a steel is used, the strain hardening during cold working is sufficiently large to obtain the required strength values for the connecting element according to the invention.
  • steels and production processes are suitable for this, as already described in the German utility model 20 2005 015 611 U1 are described.
  • screws, bolts or lock bolts according to the invention can be produced with a single production step, namely rolling. This is then the absolutely cheapest way to produce such fasteners.
  • the inventive idea of the present invention is based on having realized that made of suitable steels screws, bolts or lockbolts can be produced exclusively by a rolling operation without pressing operations.
  • the screws, bolts or locking ring bolts according to the invention can be produced directly from the raw wire after cutting the raw wire to a suitable length by rolling.
  • the rolling machine can be supplied with a corresponding washer, if they are to be fastened captive on the connecting element.
  • FIG. 1 shows a screw 10 according to the invention, which is made entirely in a single manufacturing step of rolling from a piece of wire of suitable length.
  • the external thread 12, the flange 14 and the hexalobular (external hexagon) force attack 16 were made.
  • FIG. 2 shows a likewise produced in a single manufacturing step by rolling lock bolts 20.
  • Both connecting elements according to the invention are produced in a single manufacturing step exclusively by rolling and their strength is based solely on the strain hardening during forming.
  • they are made of a steel, as for example in the German utility model 20 2005 015 611 U1 is described. Of course, other suitable steels can be used.
